Techopedia Explains RAID 2 Recovery

RAID 2 recovery is usually performed through RAID recovery software that scans each drive or array for corrupted or deleted data or hamming parity information. Typically, RAID 2 recovery requires recovering hamming code parity to restore data in the correct parity order. This information is stored on one or more parity drives. If the drives installed within the array suffered a physical problem such as head crash or spindle problem, it must be physically replaced before operation can be restored on the RAID.
